100 Réis Bronze

Angola's Provincia-era fractional notes exist because silver coinage was chronically absent from everyday commerce along the coast — Portuguese metropolitan currency rarely made it into the interior in usable quantities, and what did arrive tended to disappear into hoarding. The Provincia de Angola's paper réis were a local administrative workaround, not a formal banking product.

The "Bronze" designation in the series name refers to the metallic currency these notes were intended to substitute, not to any material property of the paper itself. Pick 20A is among the scarcer surviving pieces from this short-lived fractional issue, which was effectively obsolete once the Banco Nacional Ultramarino consolidated its circulation authority in the territory.
